Chances of natural pregnancy at 49

Razib is basically right, the time to pregnancy doesn’t change much for men from age 30 to 40. Fertility also declines in men, and I would estimate that as women age so do their partners, multiplying the chances of infertility further. I ¬†found a pregnancy probability calculator online which I cross-validated with some of the literature. When couples are trying on their own to get pregnant the fertility issue that reduces chances for success is related to the quality of the eggs. In terms of your chances of getting pregnant on day 19 of your cycle, it depends on when you ovulated.

As this information relates to the Standard Days Method, if your cycles are in the 26-32 day range then your changes of getting pregnant from intercourse on day 19 are less than 5%. That said, if you wish to avoid pregnancy, it is encouraged that you avoid unprotected intercourse on days 8 through 19! You can see a chart on this page which shows your chances for getting pregnant relative to the day you ovulate.
Both of these methods can be used by women who want to use a natural method, but don't have cycles in the 26-32 day range required to use the Standard Days Method. We can tell you that if you have sex and then ovulate 4 days later, your chances of getting pregnant are about 10-15%.

The graph at the top of this page outlines probability of getting pregnant based on when you had intercourse relative to when you ovulated.
